What is a twin entry radiator valve?

What is a twin entry radiator valve?

Also referred to as H-Block valves, our Twin Radiator Valves allow for both the water inlet and outlet to be located in one valve, this helps ensure a consistent flow of water is moved around your radiator.

Do radiator valves fit all radiators?

You’ll probably need a set of 15mm valves for your radiator, but if you’re unsure then measure the diameter of your copper pipes to double check. The connection between your valve and the radiator is standard across all moderns radiators and valves.

What are the 2 radiator valves called?

One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off. For a more detailed insight, take a look at our Radiator Valve Guide.

Do I need both valves open on a radiator?

You should open both of the valves on all of your system’s radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.

Is Microbore still used?

In modern construction microbore is once again becoming popular – but this time using plastic pipes. The pipework which circulates the water to the radiators is divided into two sections: Flow and return from the boiler to a manifold (using, say, 22mm pipes (right)).

Can you get 10mm radiator valves?

10mm radiator valves come in a range of different types to suit all homes. 10 mm radiator valves are used to connect to 10mm pipework. To enable quick and easy fitting, they are available in both angled and straight fittings.

How do I know which radiator valves to buy?

Find The Radiator Inlets The inlets are where your valves will connect the radiator to the pipework. Therefore, it’s important to look at where and how they will connect as this will determine which shape valve you need. Most radiators have valve inlets at the bottom of the radiator on each side.

What is the difference between a lockshield and radiator valve?

The Lockshield valve restricts hot water flow to radiators to help balance the entire system as a whole. Other radiator valves can be used to help adjust the temperature of a radiator to help heat or cool a room.

Do I need lockshield valve?

A lockshield valve helps to balance out that radiator and ensure the whole system is in sync, with all radiators heating at the same rate. It is therefore every bit as important a valve as without the system being balanced, there is often little point adjusting an individual temperature valve.

Should lockshield valves be fully open?

Most lockshield valves have a plastic or metal cover. You should remove these and open all of the lockshield valves completely. This requires that you turn them anticlockwise. You should also fully open the TRVs (thermostatic radiator valves).

Are Microbore pipes bad?

I’m a big fan of microbore as it reduces the volume of water in the heating system which is less water for the boiler to have to heat. People blame microbore when they start having problems but the cause is not the microbore, it’s poor maintenance and or poor installation.

Is Microbore heating any good?

Microbore is good as long as system is keeped in good order in regards to inhibitors,may be worth fitting a magnaclean filter on the system which you can clean out yourself on a regular basis.

Is Microbore any good?

Is 10mm pipe OK for central heating?

The bottom line is, if you want a modern high performance heating system in a normal sized home or larger, it’s unlikely to be achieved on 8 or 10mm pipes.

Does it matter which side of radiator flow and return?

Most modern thermostatic radiator valves are bi-directional – so can be fitted on either the flow or return pipe of your radiator. However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator.

Should a lockshield valve be on the flow or return side of a radiator?

Systems are normally balanced by adjusting the lockshield valves usually fitted on the return side of each radiator. This ensures that each radiator circuit in the system has an equal pressure drop and receives the correct flow of hot water to heat the space in which it is fitted.
